See a solution process below:

From the information in the problem we can say:

#18/25# of #175# students are likely to like the certain snack item the best.

When dealing with this type of problem the word "of" means "times" or "to multiply".

Therefore, we can rewrite and evaluate this expression as:

#18/25 xx 175 =>#

#18/25 xx (7 xx 25) =>#

#18/color(red)(cancel(color(black)(25))) xx (7 xx color(red)(cancel(color(black)(25)))) =>#

#18 xx 7 =>#

#126#

Out of 175 students #color(red)(126)# liked the certain snack.
